HERMANN ROMIINDER, OF MILWAUKEE, WISCONSIN.

I SPECIFICATION forming part of Letters Patent No. 770,114, dated September 13, 1904.

Application filed January 23, 1904.. Serial No. 190,323. (No model.)

To all whom it may concern.-

Be it known that I, HERMANN ROMI'J' DER, a citizen of the United States, and a resident of Milwaukee. in the county of Milwaukee, State of Wisconsin, have invented certain new and useful Improvements in Presses for Wood- Veneer Trunks or other Hollow Packages, of which the following is a specification.

My invention relates to machines in which under the simultaneous action of heat and pressure the overlapping portions of a number of plates of wood, generally in theform of water and weather proof wood veneer plates, are forced into intimate union with each other to form in one operation the body or lid of trunks, boxes, or other like hollow packages.

The object of my invention is to provide an efficient, economical, and rapid overlap-joining machine or press, whereby at each operation the overlapping portions of a number of Wood-veneer plates or solid-wood boards, or both, or other suitable material, preferably eight bent or curved edge plates and from five to nine straight plates ofvarious sizes and thicknesses, as may be required, may be brought under the influence of heat and pressure and by means of a suitable waterproof cementing composition applied to the overlapping parts into this homogeneous union, resulting in the formation of the body or lid of a trunk or box-shaped package which is practically seamless, simple, and cheap of construction, of greatest strength and durability, and may be used for various purposes.

'One form of my invention is shown in the accompanying drawings, in which Figure 1 is a side view of a machine or press embodying my invention. Fig. 2 is an end view of same. Fig. 3 is a top view of it; and Fig. 4 is anenlarged detail section of part of Fig. 1, showing part of the horizontally-reciprocating carriage, part of one horizontal piston and of the center'or press block, also part of two straight boards and one curved edge plate with their overlapping parts being glued together under heat and pressure.

Same letters indicate similar parts in the different drawings.

A is the framework, consisting, chiefly,

of a metal casing, which the moving parts are mounted on and connected to in suitable manner.

B, C, D, and E are pistons, each movable in a horizontal cylinder, the four cylinders being fed by one press-water-supply pipe (0, whereby all four presses operate simultaneously.

F is the piston of the vertical hydraulic press, fed by a separate press-water-supply pipe 6, whereby this press can be operated independently of and started before the horizontal hydraulic presses.

G is a carriage supported by the metal casing of the frame A and arranged to move horizontally by means of the cog-wheel H, mounted on the frame A and meshing with the rack or gear rail J, provided on the carriage G.

K K are press-plates suitably secured to the pistons B, C, D, and E of the horizontal hydraulic presses, and L L are press-plates suitably secured to the center or press block M, which block M consists of metal or other suitable material and is suitably secured to the piston F of the vertical hydraulic press. Each of these press-plates K K L Land the carriage G is provided with steam fines or chests P P, adapted to be heated by steam or other means entering through inlets 0 c and discharging through outlets dd, whereby the pressing-surfaces of the press-plates and carriage may be heated to the desired degree to act upon the material N to be pressed and the waterproof cementing composition applied to the overlapping portions of the material. This material N consists of a number of water and weather proof wood-veneer plates or solid-wood boards, or both, or other suitable material with overlapping portions 6 e, which are designed to be glued and pressed together between the press-plates K K L L and the carriage G under suflicient heat and pressure and continued thereunder for a sufiicienttime to enable them toset and become virtually integral with each other, the waterproof cementing composition with which the overlapping portions have been coated binding them together to one prac tically homogeneous piece of wood. Oounterweights O O, resting on brackets ff, when released are provided to return the pistons of the horizontal presses and the press-plates secured to said pistons as soon as the water-pressure is released, or other suitable means may be employed for this purpose.

The operation of my improved machine is as follows: The machine standing idle and the carriage Gbeing in its outer position, as shown in dotted lines in Figs. 1 and 3, and the horizontal and vertical presses being open, the number of straight and curved wood-veneer plates or material required to form the body or lid of a trunk or box-like package are placed in position over the center or press block M with its press-plates L L, the overlapping portions of the material having previously been coated with a suitable waterproof cementing composition. The carriage G is then moved forward by the cog-wheel H, which is operated mechanically by belting on tight and loose pulleys R S or otherwise from a source of power (not shown) until it reaches its inner position exactly over and covering the center or press block M with its upper press-plate L, as shown in heavy lines in Figs. 1 and 3. The piston F of the vertical press and the press-block M, suitably connected therewith, with its press-plates L L, are then sufficiently' raised, by means of operating the vertical hydraulic press through its separate press-water-supply pipe 5, until the overlapping parts of the material N between the press-plate L on top of the press-block M and the carriage Gr are thoroughly compressed. Then the four horizontal hydraulic presses are started simultaneously by operating the presswater-supply pipe to, which press the overlapping parts of the material N between the vertical press-plates K K and L L. The machine then stops and is allowed to stand, exerting this fixed pressure until the overlapping portions of the material N' have assumed permanent union and practically become one continuous homogeneousplate of wood or material, impervious to moisture and atmospheric influences, it being understood that the press-plates K K L L and the carriage G are sufliciently heated during the pressing operation by means of steam circulating through the flues or chests P or otherwise to bring about the desired result under simultaneous heat and pressure. The horizontal hydraulic presses are then opened, the water-supply through pipe at being shut oif. The pistons B, C, D, and E return by means of the counterweights O O or other means provided for this purpose. Then the vertical press is opened, the piston F moving downward of its own weight as soon as the water-pressure through pipe 6 is released, and the carriage Gr moves back to its previous outerposition by the reverse action of cog-wheel H, when the complete trunk or box may be taken from the press by lifting it from the press-plates L L on the press-block M.

The distance between opposite press-plates L L and K K and carriage Gr when the machine is open is only about one and one-half inches in practice, but may be more or less to meet requirements.

The details of operation and construction of the machinemay be varied from the above description without changing the nature of my invention so long as the separate overlapping portions of the material N are pressed and joined together into a practically homogenous piece, the material forminga complete trunk or box-like package in one operation of the machine.

- By means of inserting longer or shorter pistons B and G into the longitudinal horizontal cylinders and a center or press block M and press-plates K K L L of corresponding size, while retaining the same size lateral horizontal pistons D and E and press-plates K K L L,trunks or box-like packages of any desired length and height, but of the same width, may be produced in the same press, and the machine can be regulated to press materials of any desired thickness.

By means of this improved machine I am able to produce a large variety of structures in which any suitable material, such as plates of solid wood or wood veneer, or both, can be joined, so as to produce a continuous homogenous body,which may be of rectangular, cylindrical, oval, or such other shape as may be desired, the overlaps, owing to the waterproof cementing composition with which they have been coated and owing to the simultaneous influence of heat and pressure to which they are subjected in this machine, forming absolut'ely tight joints impervious to moisture and atmospheric influences and becoming as strong and durable as the material the trunk or box is composed of. The carriage G may also be provided with a press-plate similar to pressplates K K and L L at its base in any suitable manner.
